Synthesis of Some Bridgehead-Bridgehead-Disubstituted Bicyclo[1.1.1]pentanes
摘要:
The synthesis of a wide variety of 1,3-disubstituted bicyclo[1.1.1]pentanes is described, with particular emphasis on the generation of a series of S-X-substituted bicyclo[1.1.1]pentyl bromides required for solvolytic studies. Functional group manipulation at the bridgehead was readily accomplished in the majority of cases by radical processes in some instances, transformations were effected via carbanionic-type intermediates.

Solvolysis rates and products of 3-substituted bicyclo[1.1.1]pentyl bromides indicate extremely strong inductive charge dispersal in the ionization to bicyclo[1.1.1]pentyl-1-cations, the precursors of 3-methylenecyclobutanols.
